CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 247,973, dated October 4, 1881.

Application filed January 2;), 1881. (Model.)

To all whom it may concern:

Be it known that l, DARWIN S. VVALRATH, ot' Inghams Mills, in the county of Herkimer and State of New York, have invented a new and useful Improvement in (Jar-Couplings, of which the following is a specification.

The object of my invention is the production of a practical selt acting car-coupling device and cushioned bumper combined, which is so constructed and applied to the platform of a car that it at the same time furnishes a yielding draw-head.

In the accompanying drawings, Figure l is a longitudinal section taken on the line as w of Fig. 2 is atop View, showing the manner of securing the frame to the platform of the car. Fig. 3 is a front view. Fig.4 is a section taken on the line y y of Fig. 2. Fig. 5 is a bottom View of the bumper-head.

Similar letters of reference indicate corresponding parts.

cross-piece D. The cross-piece D has a hole, d, made through itin the center, through which the shank or stem 6 of the draw-head E passes,

and is formed with the tenons d d. The extension-pieces O U have slots 0 0 cut in them, through which the tenons e o of the drawhead E pass. The shank e of the draw-head E carries the heavy springF, which is placed between the cross-piece D and the draw-head, to force the said draw-head toward the front. The shank e is chambered, as shown in Fig. 1, and the stem or shank g of the intermediate bumper, G, with its comparatively light spring 9', passes into and is inclosed by this chamber. The intermediate bumper, G, is mounted in grooves c a, made in the extension-pieces O (l of the frame, and moves in them, for the purposes hereinafter described.

The cross-barH,which engages the connecting-bolt, is mounted in the slots a a of'the uprights A A of the frame, and is moved downward by the spring h,,surrounding the sleeve h, which latter passes up through the hole I), made in the center of the top piece, B, of the frame. The cross-bar H isopcrati-d by thele- \Ll 7c and the chains 70'. the lever provided 0 with the grooved wheel It being fulcrumed in the stud la on the top piece, B, the chains passing over the wheel and down through the slot 1) of this top piece, and being connected with loops or other fastening, i i, in the top of the cross-bar.

The bumper-head N is constructed with a flaring mouth and with a tapering opening or throat, it, entirely open on the under side, as

shown in Fig.5, the upper side being partially covered, so as to form the table a, and it is also provided on the tops with a projection, 12, for retaining it in place in the frame when the cars are uncoupled, and it may be faced with the rubber or similar material 0, for deadening the sound when the cars come together.

The frame and draw-head are mounted in the short slots 2 2, formed in the beams Z Z of the platform of the car, as shown in Fig. 2.

The connecting-link M is formed at each end with the square headsm m, adapted to engage the cross-bar H, and made with the bolt-holes m m near each end, thus adapting the link to be used with the ordinary bolt-couplings.

When the cars are ready for coupling the parts will be in the position shown in dotted lines in Fig. 1, with the cross-bar H resting on the table a, the bum perhead h avi n g been forced forward by the spring ofthe intermediate bumper when the cross-bar was raised by the lever for uncoupling. The cars to be coupled now being brought together, the connecting bolt or link M enters the mouth and th roat of the bumper-head and forces it back against the intermediate bumper and the main bumper, the springs of projection on the connecting-link, which pre- 0 vents it from being withdrawn.

It is obvious, the cross-bar B being secured in the front of the frame, the rear of the frame being mounted in the grooves in the beams of the platform of the car, and the draw-head E 5 being limited in its forward movement in said grooves, that the power for drawing the car will come against the rearward thrust of the heavyspring, and thus furnish ayielding draw for the car.

I have shown and described my improved car-coupling attached to such cars as have platforms; but itis obvious thatit may be attached to freight and other cars which have no platforms, the bottom of the car being provided With suitable beams and stays to secureit and permit its operation, and in such cases the lever for operating the cross-bar might be on the top or at the side of the car, where it may be conveniently operated.

Havingthns described my invention, Iclaim as new and desire to secure by Letters Patent- 1. In a car-coupling, a frame and a drawhead having a spring between them and both havingalimited longitudinal movementin opposite directions in the platform of the car, in

t combination with means for retaining the connecting-link, substantially as described.

2. In a oar-coupling, a frame and a drawhead separated by a spring, both having alimited movement in opposite directions in the platform of the car, in combination with the bumper-head, substantially as described.

3. In car-couplings a frame and a draw-head separated by a. spring, both having a limited movement in the platform of the car, in com bination with the bumper-head and means for restraining the connecting-bolt, substantially as described. v

4. The frame carrying the spring-actuated cross-bar H, the spring-actuated draw-head E,

andthe intermediate hunter, G, in combination with the bumper-head N,'snbstantially as set forth.

5. The frame having the extensions 0 (3, provided with the slots 00, and the cross-piece D, having the hole (1, in combination with the draw-head E, having the stem or shank 0, carrying the spring F, substantially as set forth.

6'. The draw-head E, having the chambered stem or shank e, in combination with the intermediate hum per, G, provided with a stem or shank, g, and the spring g, substantially as setforth.

7. The spring-actuated crossbar H, having the stem h and spring h, in combination with the lever is and the bumper-head N substan tially as set forth.

8. The bumper-head N, formed with the flaring mouth and the tapering throat, and with the table a and projection 02, substantially as shown and described.

9. The bumper-head N, in combination with the intermediate bumper and the cross-bar H, substai'itiallyas and for the purposes set forth.

10. Theframetormed of the grooved upright pieces AA, the top piece, 13, the slotted and grooved extensions 0 (J, and the perforated oross-piece'D, in combination with the stemmed draw-head E, stemmed intermediate bufi'er, G, crossbar H, and bumper-head N, substantially as and for the purpose set forth.
